From the second articResearchers have speculated that both droplets and aerosols generated from non-violent and violent expirations of SARS-CoV-2-infected people may be responsible for the airborne transmission of COVID-19 disease. However, more research work should be conducted to understand the behavior of virus-laden droplets and aerosols in different environmental settings, especially confined spaces so that the transmission of COVID-19 pandemic in the built environment could be fully ascertained. The case studies found worldwide indicate that the behavior of the SARS-CoV-2 virus has been unprecedentedly unique with more survival and viable rates in the air and believed to linger in the air for an extended period. The challenge before many healthcare workers in combatting the disease would be a daunting task unless proper administrative, clinical, and physical measures are taken within the healthcare settings. Inter-disciplinary research on the behavior of the SARS-CoV-2 virus needs to be conducted to prevent COVID-19 disease from spreading worldwide.le:
